FIELD: information technology.
SUBSTANCE: information transmission using a preamble of a random access channel (RACH) in an evolved universal mobile telecommunications system (E-UMTS) is provided. Preamble transmission is used to inform a base station on specific information when a terminal uses a RACH and the base station efficiently allocates radio resources for data transmission to the terminal according to the specific information.
EFFECT: reducing delay time before the terminal transmits data and avoiding excess consumption of radio resources.
